Joan Jett Rocking a Custom Teye "La Pirata"

Joan Jett was caught at a July 30 soundcheck for Jiffy Lube Live playing a custom Teye La Pirata that was specially made for her.

The guitar includes special artwork — such as black hearts — and, as the tone is precisely tailored to the gritty sounds Jett prefers, it does not have the usual Mojo or Mood knobs that offer different tonal options. Teye also added a kill switch, as Jett wants her guitar completely dead the precise moment that a song ends.

How did this guitar get into Jett's hands? Fun fact on that one: Teye's Evert Wilbrink signed Jett to her first solo-artist record deal in the early '80s, and has had a long-standing professional relationship with the iconic artist, who just celebrated the 42nd anniversary of her band The Runaways forming on August 5.
